K6TU Remote - Sneak Preview

Here is a short video as a sneak preview of the new iPad app I'm working on - K6TU Remote - for full remote control of the Flex-6000 series radios over LAN and WAN (Internet VPN required with adequate performance).

Some likely questions and related answers...

What does the App work on?
The app works on the Apple iPad.  Testing is still in process but its likely that the app will require Apple Metal (graphics engine and GPU) for adequate performance.  This probably means an iPad Retina or more recent unit.  The software works on an iPad Mini but performance is not acceptable to me.

When will the App be available?
Probably in a couple of months - all the heavy lifting is done but I want the UI experience to be uncluttered, natural and easy to use.

Will there be an alpha/beta version?
Yes - but all the alpha and beta test slots are already committed - sorry.

Will the App be free?
Free?  Like in free ****? No - there will be a "lite" version of the App which will be a free download from the App Store but it will only support receive operation and a single slice.  The full function App will be available for purchase on the App Store at a price higher than the current K6TU Control App.  The final price is still being debated.

Describe the App
K6TU Remote at the first release will support a single pan adaptor (with waterfall) and a maximum of TWO slices.  You will be able to make CW and Phone QSOs - there is no digital support for modes like PSK, RTTY etc although you can use this App in parallel with SmartDAX & SmartCAT running on a computer.  It is likely that there will be no CW sidetone at the first release - you will see the CWX typed characters change color as they are sent.  You will NOT be able to use SmartSDR at the same time as you are using K6TU Remote - the current radio firmware supports a single GUI client at a  time.

Will the be an Android version of K6TU Remote?
No.  I don't have the cycles to be able to support Android devices - sorry.  However, there are others working on GUI apps for Android as you can see by searching the Community.

But I have many more questions! :-)
Alas GrassHopper I have used today's quota of answers.  Answer rationing is in effect here in California so tomorrow doesn't look too good either... ;-)  I will do my best to answer questions but I'm in the coding process and working like fury to get the alpha out to the testers so please excuse me if the answers aren't by return.

Thanks for looking and hope it whets your appetite!
Stu K6TU

PS: The waterfall renders really nicely but looks a little washed out in the video.  I will post some high res video stream captures when I have time.

    WAN remote NOW using the VPN solution I described. I will of course add v2.0 WAN support when FlexRadio releases it. I made two QSOs today from my office remotely to my radio. Worked great as the SoftEther server supports the iPad native VPN support. No additional software required. Woot! Stu K6TU

    Fantastic.  I have the iPad app now and use it a lot.  Having direct control is really nice in a contest.  I am really looking forward to this app.  Program faster.  :)

    Looks great Stu!  The only thing that I can offer is that (in my estimation) the Pinch In and Pinch Out functions should be reversed for zooming in or out. 

    Great job Stu!   I can hardly wait for the completion and release.

    Jay, I thought it was just me but it seemed backwards as well.

      I'm sold (If I can afford it and the Maestro)!

      Very nice job, so far.

    PS: I also think the pinch is backward. (It just feels more natural to have the display move the same way as the fingers).

    Will this be an upgrade to the existing app or a new app entirely?

    This is a new App and K6TU Control will continue to be used for radio control in conjunction with SmartSDR.  The two apps are intended for different purposes.

    Stu, the finger pinch seems counter intuitve.  On my MacBook Pro opening the fingers magnifies the screen and closing them make the object look smaller.  Do you have the option of reversing the way the gesture works?  Very nice, BTW.

    Alan, With the the same comment now from several folks, I will reverse the effect. It's just a simple matter of programming :-). Shouldn't be too difficult. I appreciate the feedback on this feature! I want this app to be uncluttered and very easy to use so these feedback a especially at this stage really help. Stu K6TU

    Stu, one option that might be helpful and still accomplish your goal of keeping the app uncluttered is to create a hotspot for the left and right side or top left and right corner.

    By touching a hotspot it would slide out addition controls or instructions on the touch commands.

    For Example: Touching the right border would slide out a panel and activate the keyboard so you can enter the frequency directly and/or other functions.

    If you need any GUI or graphics help let me know. I would be happy to create a few screen mock ups.

    Do you have my office bugged? ;-)  What I'm implementing is very similar to your comment:
    • Swipe from the left side of the screen to present the transmitter controls
    • Swipe from the right side to present the receiver controls
    • Swipe down from the top for miscellaneous controls like disconnect, setup
    • Tap on the heads up display to get direct frequency input
    • Hot spot on left side of screen to get quick access to display controls
    At least that is the current plan.

    CW operation will be a little different with the presentation of a CW specific keyboard and an area for type ahead/see what you sent.  I'm still thinking about exactly how this will be presented as it will need most of the screen given usable finger sized "keys".

    Stu When I remote via Bluetooth headset to my iPad , I tend to prefer to use VOX rather than a MOX button when feasible Be great if one had both options.

    Ooops did I accidentally reveal that I work for the NSA. Darn I hate when happens. LOL

    Sorry no bugs just a keen sense of understanding on how valuable limited screen real estate is and whats involved in implementation. Every pixel on a screen is valuable and most people do not realize when you have a list of 20 features and functions that when you implement or move one that affects the 19 other controls. :)

    VOX already works and will have controls to turn it on as an option.  I had also hoped to use the button on the Apple supported remote control (the audio controls on the earbuds, head sets etc) but alas that's not looking possible.  Seems that Apple doesn't want the functionality of that control being over ridden from the audio player.

    Much to my chagrin...

    Great to see this add-on in development.  I use the K6TU Control App but having (almost) full remote operating capability on an iPad would be a wonderful addition to the setup.  Good for FlexRadio and hopefully some pennies towards Stu’s time and troubles!

    I have already pre-ordered. ;-)

    I hope the radio chooser includes the Nickname and / or the callsign. At Field Day this year we had two 6700's and we did not have our serial numbers memorized.

    Once again you have knocked it out of the park. I want to set my truck up for remote as soon as 2.0 is out although I might goahead and do it with your set up you posted. But I really wanted to use the iPad. The main thing we need is a hard ptt for Mobil blue tooth head set or wired headset is fine and vox is fine but a ptt is required.

    The statement about which pad will work is disappointing ing since I have a ipad2 and if it was stolen out of truck or damaged it would not hurt. I do not wish to run multiple slices mobil so is this a definite that I will need to upgrade?

    Also will the flex knob be able to interface with the ipad?
